IMPROVEMENT IN GRAIN-DRYERS.

, l TO ALL WHOM ITMAY'OONCERN: i

Be it known that I, LEWIS S. Cmonns'rnn, of Brooklyn, in the county of Kings, and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Grain-Dryers; and I do l'iereby cleelare the following to he a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this, specification, wherein- Figure 1 is a vertical section of my improved grain drying apparatus.

Figure 2 is a vertical section transversely of the fire-chamber; and

Figure 3 is a vertical section transversely of the grain-chambers.

Similar marks of reference deiiote' the same parts. i

In Letters Patent granted August 15, 1865, for a grain-dryer invented by me, a series of inclined tables is employed, and the heated air passes over the grain and beneath the next table above, so as to heat the tables and the grain, and convey away the moisture evaporated from the grain. And in Letters Patent granted May 2, 1865, for a graindryer invented by me, the tables upon which the grain falls are inclined, and alternately converge and diverge. My present invention is an improvement upon these said grain-dryers, and consists in a peculiar heating-chamber for the air that is passed to the grain; also in an arrangement of air-passages and which it is allowed to run away at the lower part of the dryer, and by this means the extentof the drying operation may be regulated according to circumstances.

What I claim, and desire to secure by Letters Patent, is-

1, In a grain-drying apparatus I claim a chamber above the fire, into which air is admitted in large volumes, and descends and mingles with the products of combustion and passes into the grain-dryer, substantially as and for the purposes specified.

2. I claim the arrangement of the hot and cold-air flues f and n, trunks g or g, and ralves Z1 and m m, for regulating the temperature of the air passing into the grain-drying chamber is, substantially as specified.

3. I claim a series of half pipes crossing the grain-chamber, and openingat or near both ends into airspaccs or fiues, asset forth, so that the current of air shall pass through and beneath the half tubes and in contact with the grain, as set forth.

In witness whereof. Ihave hereunto set my signature this twenty-fourth day of November, A. D. 1866.
